Thus, in some cases, the gel does not include a flavor soluble solvent.

The amorphous solid may include fillers. Taken together, amorphous solids typically include gelling agents and fillers (if present) in an amount of about 10 to 60 wt % of the amorphous solid. In examples, the amorphous solid comprises filler in an amount of 1 to 15 wt % of the amorphous solid, such as 5 to 15 wt %, or 8 to 12 wt %. In examples, the amorphous solid includes filler in an amount greater than 1 wt %, 5 wt %, or 8 wt % of the amorphous solid. In some embodiments, the amorphous solid comprises less than 60 wt % filler, such as 1 wt % to 60 wt %, or 5 wt % to 50 wt %, or 5 wt % to 30 wt %, or 10 wt % to 20 wt %.

In other embodiments, the amorphous solid comprises less than 40 wt %, less than 20 wt %, suitably less than 10 wt % or less than 5 wt % filler. In some cases, the amorphous solid comprises less than 1 wt % filler, and in some cases no filler.

The filler, if present, may be one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable suitable such as molecular sieves. Inorganic adsorbents may be included. The filler may include one or more organic filler materials such as wood pulp, cellulose and cellulose derivatives. In special cases, the amorphous solid does not include calcium carbonate, such as chalk.

In certain embodiments comprising a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler material such as wood pulp, hemp fiber, cellulose or cellulose derivatives. Without wishing to be bound by theory, it is believed that the inclusion of fibrous fillers in the amorphous solid may increase the tensile strength of the material.

In some embodiments, the amorphous solid is cannabidiol (CBD), tetrahydrocannabinol (THC), tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), cannabinol (CBN), cannabigerol (CBG), cannabichromene (CBC), cannabicyclol (CBL). ), CBV (cannabivarin), THCV (tetrahydrocannabivarin), CBDV (cannabidivarin), CBCV (cannabichromevarin), CBGV (cannabigerovarin), CBGM (cannabigerol monomethyl ether) and at least one selected from the group consisting of CBE (cannabielsoin), CBT (cannabicitran) including cannabinoid compounds.

In some instances, such as when the amorphous solid does not include a filler, the amorphous solid has an amount of 150 N/m to 500 N/m, or 200 N/m to 400 N/m, or 200 N/m to 300 N/m, or about 250 N/m. It may have tensile strength. Such tensile strengths may be particularly suitable for embodiments in which an amorphous solid material is formed into a sheet and then crushed to be incorporated into an aerosol-generating article.

In some instances, such as when the amorphous solid comprises a filler, the amorphous solid is from 150N/m to 3000N/m, such as from 500N/m to 1200N/m or from 600N/m to 900N/m, or from 700N/m to 900N. /m, or a tensile strength of about 800 N/m. In some examples, the amorphous solid can have a tensile strength greater than 500 N/m, greater than 1000 N/m, or greater than 1500 N/m. These tensile strengths may be particularly suitable for embodiments in which the amorphous solid material is incorporated into the aerosol-generating article as a rolled sheet, suitably in the form of a tube.

In certain embodiments, the amorphous solid comprises a cellulosic gelling agent and/or a non-cellulosic gelling agent, a gelling agent comprising an active substance and an acid.

In some cases, the amorphous solid consists essentially of or may consist of a gelling agent, water, an aerosol former material, a flavor, and optionally an active substance.

In some of these embodiments, the acid may be a mineral acid. In some such embodiments, the acid may be at least one of sulfuric acid, hydrochloric acid, boric acid, and phosphoric acid. In some embodiments, the acid is levulinic acid.

The inclusion of an acid is particularly preferred in embodiments where the amorphous solid comprises nicotine. In such embodiments, the presence of the acid may stabilize the dissolved species in the slurry from which the aerosol generating material is formed. The presence of the acid may reduce or substantially prevent evaporation of nicotine during drying of the slurry, thereby reducing loss of nicotine during manufacture.

The amorphous solid may include a colorant. The addition of colorants can change the visual appearance of the amorphous solid. The presence of colorants in amorphous solids can enhance the visual appearance of amorphous solids and aerosol generating materials. By adding a colorant to the amorphous solid, the amorphous solid can be color-matched with other components of the aerosol generating material or with other components of an article comprising the amorphous solid.

Various colorants may be used depending on the desired color of the amorphous solid. The color of the amorphous solid may be, for example, white, green, red, purple, blue, brown or black. Other colors are also envisioned. Natural or synthetic colorants may be used, such as natural or synthetic dyes, food-grade colorants and pharmaceutical-grade colorants. In certain embodiments, the colorant is caramel, which can give an amorphous solid with a brown appearance. In such embodiments, the color of the amorphous solid may be similar to the color of other components of the aerosol generating material comprising the amorphous solid (eg, tobacco material). In some embodiments, the addition of a colorant to the amorphous solid renders the amorphous solid visually indistinguishable from other components of the aerosol generating material.

The colorant may be incorporated during the formation of the amorphous solid (eg, when forming a slurry comprising materials that form the amorphous solid) or (eg, by spraying the colorant onto the amorphous solid) or the formation of the amorphous solid. It can then be applied to the amorphous solid.

The one or more other functional materials may include one or more of pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and/or antioxidants.

The consumable may also include an aerosol generator, such as a heater, that emits heat so that the aerosol generating material generates an aerosol in use. The heater may include, for example, a combustible material, a material heatable by electrical conduction, or a susceptor.

A susceptor is a material that can be heated by penetration by a changing magnetic field, such as an alternating magnetic field. The susceptor may be an electrically conductive material, such that its penetration by a changing magnetic field causes inductive heating of the heating material. The heating material may be a magnetic material, such that penetration by a changing magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically conductive and magnetic, such that the susceptor is heatable by both heating mechanisms. A device configured to generate a changing magnetic field is referred to herein as a magnetic field generator.

Aerosol modifiers are substances, typically located downstream of the aerosol generating region, configured to modify the aerosol generated, for example, by altering the taste, flavor, acidity or other properties of the aerosol. The aerosol modifier may be provided in an aerosol modifier releasing component that is operable to selectively release the aerosol modifier.

The aerosol modifier may be, for example, an additive or an adsorbent. Aerosol modifiers may include, for example, one or more of flavoring agents, colorants, water and carbon adsorbents. The aerosol modifier may be, for example, a solid, liquid or gel. The aerosol modifier may be in powder, thread or granular form. The aerosol modifier may be free of filtration material.

An aerosol generator is a device configured to generate an aerosol from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to apply thermal energy to the aerosol-generating material to release one or more volatile substances from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol generating material without heating. For example, the aerosol generator may be configured to apply one or more of vibration, increased pressure, or electrostatic energy to the aerosol generating material.

They are also named according to product circumference: "regular" (about 23-25 mm), "wide" (greater than 25 mm), "slim" (about 22-23 mm), "demi-slim" slim)" (about 19-22 mm), "super-slim" (about 16-19 mm), and "micro-slim" (less than about 16 mm).

Thus, a king-size, super-slim type article would, for example, have a length of about 83 mm and a circumference of about 17 mm.

Each type can be made with mouthpieces of different lengths. The mouthpiece length will be between about 30 mm and 50 mm. The tipping paper connects the mouthpiece to the aerosol generating material and will generally have a longer length than the mouthpiece, for example 3 mm to 10 mm longer, so that the tipping paper covers the mouthpiece, and yes It overlaps with the aerosol generating material, for example in the form of a rod of base material, to connect the mouthpiece to the rod.

The articles described herein and their aerosol generating materials and mouthpieces may be made in any of the above formats, but are not limited to this.

As used herein, the terms 'upstream' and 'downstream' are relative terms defined for the direction of the mainstream aerosol drawn through the article or device in use.

The filler component may be wood fibers or non-tobacco fibers such as pulp or wheat fibers. The filler component may also be an inorganic material such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate. The filler component may also be a non-tobacco cast material or a non-tobacco extruded material. The filler component may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1 to 10% by weight of the total composition, eg, the aerosol generating material described herein. In some embodiments, no filler component is present.

In the tobacco material described herein, the tobacco material has an aerosol former material.

In some embodiments, the aerosol former material of the tobacco material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol is present in an amount of 10% to 20% by weight of the tobacco material, for example 13% to 16% by weight of the composition, i.e. the total aerosol generating material described herein, or about 14% or 15% by weight of the composition. may exist. Propylene glycol, if present, may be present in an amount from 0.1% to 0.3% by weight of the composition.

The aerosol former material may be included in any component of the tobacco material, for example any tobacco component and/or, if present, the filler component. Alternatively or additionally, the aerosol former material may be added separately to the tobacco material. In either case, the total amount of aerosol former material in the tobacco material may be as defined herein.

The tobacco material may contain from 10% to 90% by weight of tobacco leaves, for example tobacco lamina. In addition to any aerosol former material provided via the amorphous solid material, the tobacco material may be provided with an aerosol former material. For example, an aerosol former material as described herein may be provided to the tobacco material in an amount of from 2% to 20% by weight of the tobacco material, such as from about 5% to about 15% by weight. When tobacco leaves are used, the aerosol former may comprise up to about 10% by weight of the leaf tobacco. It has advantageously been found that in order to achieve a total level of aerosol former material of 10% to 20% by weight of the tobacco material, it can be added in higher weight percentages to other components of the tobacco material, such as the reconstituted tobacco material. . In some examples, the tobacco material consists essentially of leaf tobacco, such as lamina tobacco.

The tobacco material described herein retains nicotine. The nicotine content may be 0.5% to 1.75% by weight of the tobacco material, for example 0.8% to 1.5% by weight of the tobacco material. Additionally or alternatively, the tobacco material has from 10% to 90% by weight tobacco leaves having a nicotine content greater than 1.5% by weight of the tobacco leaves. Advantageously, the use of tobacco leaves with a nicotine content of greater than 1.5% in combination with a low nicotine content base material such as paper reconstituted tobacco provides adequate nicotine levels to the tobacco material, but rather than using paper reconstituted tobacco alone. It has been found to provide better sensory performance. For example, tobacco leaves, such as cut rag tobacco, may have, for example, a nicotine content of between 1.5% and 5% by weight of tobacco leaves.

Tobacco material described herein may have an aerosol modifier such as any of the flavors described herein. In one embodiment, the tobacco material retains menthol to form an article comprising menthol. The tobacco material may contain 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, more preferably 8 mg to 16 mg of menthol. In this example, the tobacco material contains 16 mg of menthol.

In one embodiment, the tobacco material comprises 4.7% menthol by weight. Such high levels of menthol loading can be achieved using a high percentage of reconstituted tobacco material, for example greater than 50% by weight of the tobacco material. Alternatively or additionally, the use of a high volume of aerosol-generating material, eg, tobacco material, is for example when greater than about 500 mm 3 or suitably greater than about 1000 mm 3 of aerosol-generating material such as tobacco material is used. , can increase the level of menthol loading that can be achieved.

In compositions or aerosol generating materials described herein, where amounts are provided in weight percent, for the avoidance of doubt, this is meant on a dry weight basis, unless specifically indicated otherwise. Thus, any moisture that may be present in the tobacco material or any component thereof is completely neglected for purposes of weight percent determination. The moisture content of the tobacco material described herein can vary, for example, from 5 to 15% by weight. The moisture content of the tobacco material described herein may vary depending on, for example, the temperature, pressure and humidity conditions in which the compositions are maintained. The water content can be determined by Karl-Fisher analysis as known to those skilled in the art. On the other hand, for the avoidance of doubt, even if the aerosol former material is a liquid component such as glycerol or propylene glycol, any component other than water is included in the weight of the tobacco material. However, when the aerosol former material is provided to the tobacco component of the tobacco material or the filler component of the tobacco material (if present), instead of or in addition to being separately added to the tobacco material, the aerosol former material may comprise a tobacco component. It is not included in the weight of the element or filler component, but is included in the weight of "aerosol former material" in weight percent as defined herein. All other ingredients present in the tobacco component, even if of non-tobacco origin (eg non-tobacco fibers in the case of paper reconstituted tobacco), are included in the weight of the tobacco component.

In one embodiment, the tobacco material comprises a tobacco component as defined herein and an aerosol former material as defined herein.

In embodiments, the paper reconstituted tobacco is present in an amount from 10% to 80% by weight of the tobacco component, or from 20% to 70% by weight. In a further embodiment, the tobacco component consists essentially of or consists of paper reconstituted tobacco. In a preferred embodiment, the leaf or lamina tobacco is present in the tobacco component of the tobacco material in an amount of at least 10% by weight of the tobacco component. For example, leaf tobacco may be present in an amount of at least 10% by weight of the tobacco component, with the remainder of the tobacco component being paper reconstituted tobacco, bandcast reconstituted tobacco, or other forms such as bandcast reconstituted tobacco and tobacco granules. Contains a combination of cigarettes. Suitably, the leaf tobacco may be present in an amount of 40% or 60% by weight of the tobacco material, while the remainder of the tobacco component is combined with paper reconstituted tobacco, bandcast reconstituted tobacco, or bandcast reconstituted tobacco and tobacco granules. The same includes combinations of different types of cigarettes.

Paper reconstituted tobacco refers to tobacco material formed by a process of extracting a tobacco feedstock with a solvent to provide a residue comprising an extract of solubles and a fibrous material, which is then extracted (usually after concentration and optionally further processing). After) deposits the extract on the fibrous material (usually after purification of the fibrous material, and optionally with the addition of some of the non-tobacco fibers) to recombine with the fibrous material from the residue. The recombination process is similar to the papermaking process.

The paper reconstituted tobacco may be any type of paper reconstituted tobacco known in the art. In a particular embodiment, the paper reconstituted tobacco is manufactured from a feedstock comprising one or more of tobacco strips, tobacco stems, and whole leaf tobacco. In a further embodiment, the paper reconstituted tobacco is prepared from a feedstock consisting of tobacco strips and/or whole leaf tobacco, and tobacco stems. However, in other embodiments, scraps, fines and winnowings may alternatively or additionally be used in the feedstock.

In the drawings described herein, like reference numbers are used to illustrate equivalent features, articles, or components.

1 is a cross-sectional side view of an article 1 for use in an aerosol delivery system.

The article 1 comprises a mouthpiece 2 and a cylindrical rod of aerosol generating material 3 connected to the mouthpiece 2 . In exemplary embodiments of the invention, the aerosol generating material comprises a blend of at least two distinct components. In some embodiments, the aerosol generating material comprises a plurality of strands and/or strips of tobacco material, and a plurality of strips of amorphous solid material, wherein the plurality of strands and/or strips of tobacco material and an amorphous solid Each of the plurality of strips of material has a length of at least about 5 mm. In some embodiments, the material properties and/or dimensions of the at least two components enable relatively uniform mixing of the component and prevent separation or non-mixing of the component during or after manufacture of the rod of aerosol generating material. It may be appropriately selected in other ways to reduce.

Although described above in rod form, the aerosol generating material may be provided in other forms, such as a plug, pouch, or packet of material within an article. The article may include consumables for an aerosol delivery or delivery system, such as a non-flammable aerosol delivery or delivery system as described herein.

In this example, the first component is a tobacco material and the second component is an amorphous solid material.

In some examples, the tobacco material comprises paper reconstituted tobacco material. Tobacco material may alternatively or additionally include any of the forms described herein. Preferably, the tobacco material may have from 10% to 90% by weight tobacco leaves, and the aerosol former material is provided in an amount up to about 10% by weight of the leaf tobacco. Such aerosol formers may be provided in addition to aerosol formers provided in the amorphous solid material. For example, 3% to 8%, or 4% to 7%, or 5% to 7% by weight of the tobacco material may be used. The remainder of the tobacco material may comprise paper reconstituted tobacco. In other examples, the tobacco material comprises up to 100% tobacco leaves, for example up to 100% tobacco lamina, which may be in the form of cut rag tobacco. It may be advantageous to adjust the moisture content of the aerosol former and/or the tobacco lamina material to avoid materials that are too dry and too brittle. For example, tobacco lamina may comprise 5% to 8% aerosol former such as glycerol and/or 9% to 12% water. In this example, the amorphous solid material is a dry gel comprising menthol. In alternative embodiments, the amorphous solid may have any composition as described herein.

The inventors have discovered that advantageously improved articles comprising an aerosol generating material comprising a first component comprising tobacco material and a second component comprising an amorphous solid can be generated, the material properties (eg, density) and specifications (eg, thickness, length and cut width) fall within the ranges presented herein.

In some cases, the amorphous solid may have a thickness of from about 0.015 mm to about 1.5 mm. Suitably, the thickness may range from about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm, 0.3 mm or 1 mm. The inventors have found that materials having a thickness of about 0.2 mm can be used. An amorphous solid may include more than one layer, and the thicknesses described herein refer to the collective thickness of such layers.

The thickness of the amorphous solid material can be measured using calipers or a microscope, such as a scanning electron microscope (SEM), or any other suitable technique known to those skilled in the art.

The inventors have established that heating efficiency is compromised if the amorphous solid is too thick. This can negatively affect power consumption during use, for example power consumption to release flavor from an amorphous solid. Conversely, if the aerosol-forming amorphous solid is too thin, it can be difficult to manufacture and handle; Very thin materials are more difficult to cast and are brittle, impairing aerosol formation in use. The inventors have established that the amorphous solid thicknesses defined herein optimize material properties in light of these conflicting considerations.

In some cases, an individual strip or piece of amorphous solid has a minimum thickness over an area of about 0.015 mm. In some cases, an individual strip or piece of amorphous solid has a minimum thickness over an area of about 0.05 mm or about 0.1 mm. In some cases, an individual strip or piece of amorphous solid has a maximum thickness over an area of about 1.0 mm. In some cases, an individual strip or piece of amorphous solid has a maximum thickness over an area of about 0.5 mm or about 0.3 mm.

The inventors have found that providing tobacco material and amorphous solids having areal density values that differ from each other by less than a given percentage result in less segregation in the mixture of these materials. In some examples, the areal density of the amorphous solid material may be between 50% and 150% of the areal density of the tobacco material. For example, the areal density of the amorphous solid material may be between 60% and 140% of the density of the tobacco material, or between 70% and 110% of the areal density of the tobacco material, or between 80% and 120% of the areal density of the tobacco material. .

For the avoidance of doubt, when reference is made to areal density herein, it refers to the average areal density calculated for a given strip, piece or sheet of amorphous solid material, the areal density being a given strip, piece or sheet of amorphous solid material. or by measuring the surface area and weight of the sheet.

In some cases, the amorphous solid thickness may vary by no more than 25%, 20%, 15%, 10%, 5%, or 1% over the region.

In embodiments described herein, the amorphous solid material may be incorporated into an article in the form of a sheet. The amorphous solid material in the form of a sheet may be crushed, then incorporated into an article, and suitably mixed into an aerosolable material such as tobacco material (as further described below).

In further embodiments, the amorphous solid sheet may additionally be included as a flat sheet, a gathered or bundled sheet, a crimped sheet, or a rolled sheet (ie, in the form of a tube). In some such cases, the amorphous solid of these embodiments may be included in an aerosol-generating article as a sheet, such as a sheet surrounding a rod of aerosol-capable material (eg, tobacco). For example, an amorphous solid sheet may be formed on a wrapping paper surrounding an aerosolable material such as a cigarette.

The amorphous solid in sheet form may have any suitable areal density, such as from about 30 g/m 2 to about 150 g/m 2 . In some cases, the sheet is from about 55 g/m to about 135 g/m, or from about 80 to about 120 g/m, or from about 70 to about 110 g/m, or from about 100 g/m to about 125 g/m, or particularly from about 90 to It may have a mass per unit area of about 110 g/m 2 , or suitably about 100 g/m 2 , 120 g/m 2 , or 110 g/m 2 . These ranges can provide densities similar to those of cut rag cigarettes, resulting in mixtures of these materials that will not readily separate. These areal densities may be particularly suitable when the amorphous solid material is incorporated into the aerosol-generating article as a shredded sheet (described further below). In some cases, the sheet may have a mass per unit area of about 30 to 70 g/m, 40 to 60 g/m, or 25 to 60 g/m and may be used to wrap an aerosol capable eg cigarette.

The density of the tobacco material affects the rate at which heat is conducted through the material, with lower densities, e.g., densities below 700 mg/cc, conducting heat through the material more slowly, and thus a longer lasting aerosol. enable release.

The tobacco material may comprise reconstituted tobacco material, eg, paper reconstituted tobacco material, having a density of less than about 700 mg/cc. For example, the aerosol generating material 3 comprises reconstituted tobacco material having a density of less than about 600 mg/cc. Alternatively or additionally, the aerosol generating material 3 may comprise reconstituted tobacco material having a density of at least about 350 mg/cc.

The tobacco material may be provided in the form of cut rag tobacco. A cut rag cigarette may have a cut width of at least 15 cuts per inch (about 5.9 cuts per cm, corresponding to a cut width of about 1.7 mm). Preferably, the cut rag cigarette has a cut width of at least 18 cuts per inch (about 7.1 cuts per cm, corresponding to a cut width of about 1.4 mm), more preferably a cut width of at least 20 cuts per inch (about 7.9 cuts per cm, Corresponding to a cut width of about 1.27 mm). In one example, the cut rag cigarette has a cut width of 22 cuts per inch (about 8.7 cuts per cm, corresponding to a cut width of about 1.15 mm). Preferably, the cut rag cigarette has a cut width of 40 cuts per inch (about 15.7 cuts per cm, corresponding to a cut width of about 0.64 mm) or less. The cut widths of 0.5 mm to 2.0 mm, for example 0.6 to 1.7 mm, or 0.6 mm to 1.5 mm, are suitable for the surface area to volume ratio of the aerosol generating material 3 , especially when heated, and in terms of overall density and pressure drop. It has been found to preferably produce tobacco material. The cut rag tobacco may be formed from a mixture of forms of tobacco material, for example, a mixture of one or more of paper reconstituted tobacco, leaf tobacco, extruded tobacco and bandcast tobacco. Preferably the tobacco material comprises paper reconstituted tobacco or a mixture of paper reconstituted tobacco and leaf tobacco.

The tobacco material may have any suitable thickness. The tobacco material may have a thickness of at least about 0.145 mm, such as at least about 0.15 mm, or at least about 0.16 mm. The tobacco material may have a maximum thickness of about 0.25 mm, for example, the thickness of the tobacco material may be less than about 0.22 mm, or less than about 0.2 mm. In some embodiments, the tobacco material may have an average thickness in the range of 0.175 mm to 0.195 mm. This thickness may be particularly suitable where the tobacco material is a reconstituted tobacco material.

It may be desirable to provide an aerosol generating material comprising a blend of at least two components, such as a first component comprising a tobacco material as described herein and a second component comprising an amorphous solid material. Such aerosol-generating materials can provide an aerosol with a desirable flavor profile in use, since additional flavor can be introduced into the aerosol-generating material by inclusion in the amorphous solid material component. The flavor provided to the amorphous solid material can be more stably retained in the amorphous solid material as compared to flavor added directly to the tobacco material, resulting in a more consistent flavor profile between articles generated in accordance with the present invention.

As mentioned above, tobacco material having a density of at least 350 mg/cc and less than about 700 mg/cc has been found to advantageously result in a more sustained release of the aerosol. In order to provide an aerosol with a consistent flavor profile, the amorphous solid material component of the aerosol generating material must be evenly distributed throughout the rod. The inventors have advantageously cast the amorphous solid material such that it has a thickness as described herein to provide an amorphous solid material having an areal density similar to that of a tobacco material and is uniform throughout the aerosol generating material. It has been found that this can be achieved by processing an amorphous solid material as described below to ensure distribution.

The inventors have advantageously found that a sufficiently uniform mixing of the tobacco material component and the amorphous solid material component can be achieved when the amorphous solid material in the form of a sheet is crushed. Preferably, the cut width of the crushed amorphous solid material is between 0.75 mm and 2 mm, for example between 1 mm and 1.5 mm. Strands of the amorphous solid material formed by fracturing may be cut in the width direction, for example in a cross-cut type fracturing process, to define a cut length for the crushed amorphous solid material in addition to the cut width. The cut length of the crushed amorphous solid material is preferably at least 5 mm, for example at least 10 mm, or at least 20 mm. The cut length of the crushed amorphous solid material may be less than 60 mm, less than 50 mm, or less than 40 mm. The inventors have found that, in order to achieve uniform mixing of the crushed amorphous solid material and the cut rag tobacco, advantageously, the cut length of the crushed amorphous solid material is preferably non-uniform. For example, the distribution of cut lengths may be a multimodal distribution, such as a bimodal distribution. In some examples, a first portion of the amorphous solid material can be cut to a first length, a second portion of the amorphous solid material can be cut to a second length, and the cut materials are mixed together to form a bimodal distribution of lengths. form a plurality of strands or strips of amorphous solid material having In some examples, the first cut length can be between 30 mm and 50 mm, or between 35 mm and 45 mm, or about 40 mm, and the second cut length can be between 10 mm and 30 mm, or between 15 mm and 25 mm, or about 20 mm. The number of cut lengths may be selected to match the number of modes of length distribution of the shredded tobacco material. Strands of amorphous material having different cut lengths may be mixed together in a proportion selected to match the distribution of lengths of shredded tobacco material. The inventors have discovered that matching the distribution of the lengths of the strands and/or strips of the amorphous solid material with the distribution of the lengths of the strands of the tobacco material can result in a much more uniform mixing of the amorphous solid and the tobacco material.

Although referred to as cut length, the length of the pieces or strips of amorphous solid material may alternatively or additionally be dictated by the dimensions of the material determined during its manufacture, eg the width of the sheet of material produced.

In some embodiments, a plurality of strips of amorphous solid material is provided and at least one of the plurality of strips of amorphous solid has a length greater than about 10 mm. At least one of the plurality of strips of amorphous solid material may alternatively or additionally have a length of from about 10 mm to about 60 mm, or from about 20 mm to about 50 mm. Each of the plurality of strands or strips of amorphous solid material may have a length of from about 10 mm to about 60 mm, or from about 20 mm to about 50 mm.

Preferably, the rod of aerosol generating material comprises a first component comprising tobacco material in an amount of 50% to 98%, such as 80% to 95%, wherein the tobacco material is provided for example as a cut rag tobacco and and a second component comprising crushed amorphous solid material in an amount of 2% to 50%, for example 5% to 20%.

The inventors have found that it may be advantageous for manufacturing to form a rod of an aerosol aerosol generating material from a relatively small amount within the range set forth herein of crushed amorphous solid material comprising a relatively high level of an aerosol forming agent within the range set forth herein. and, therefore, for a given aerosol former content of an aerosol generating material, fewer strips of amorphous solid material are required. This can be advantageous in manufacturing because relatively more tobacco material is in contact with the components of the manufacturing machine compared to the amorphous solid material, which can reduce the likelihood of material clumping in the machine and/or clogs formed during manufacturing. For example, the amount of an aerosol former such as glycerol in the amorphous solid material may be 20% to 70% by weight of the amorphous solid material, for example 25% to 55% by weight, 30% to 40% by weight or 45% by weight of the amorphous solid material. to 55% by weight.

The inventors have found that, advantageously, an aerosol generating material according to the present disclosure can have a more uniform distribution of the crushed amorphous solid material throughout the aerosol generating material. For example, the standard deviation (expressed as a percentage of the mean) as a percentage of the weight inclusion level of strips of amorphous solid material in the aerosol-generating material between consumables manufactured using the aerosol-generating material as described herein is: Based on a measurement of 10 consumables in this case each holding about 650 mg of aerosol generating material, it may be less than 35%, or less than 30%, by weight of the aerosol generating material. Table 1a shows that for three aerosol generating materials: Material A with an average amorphous solids content of 4.6307%, Material B with an average amorphous solids content of 10.625%, and Material C with an average amorphous solids content of 19.722%. Shows the % inclusion achieved. For example, for average amorphous solids inclusion rates greater than 10%, it has been found that a standard deviation of less than 30% as a percentage of the mean can be achieved. The measurement is performed by carefully opening the aerosol generating material rod of the consumables and manually separating the amorphous solid material from the tobacco material.

Exemplary aerosol generating materials were prepared according to the present disclosure, and chemical analysis was performed on a sample of each exemplary aerosol generating material to determine the total nicotine, glycerol and moisture content of the material, as known to those skilled in the art. . Ten samples of 10 g were taken from a batch of aerosol generating material for chemical analysis and their average nicotine, glycerol and water content and standards within the batch of aerosol generating material prepared according to the methods described herein. The process was repeated 10 times to obtain the deviation.

Each of the exemplary aerosol generating materials 1 to 3 comprises 100% leaf tobacco as a tobacco material component, and was manufactured with different specifications in terms of the inclusion level of the amorphous solid material component and the composition of the amorphous solid material, respectively. Tobacco material included glycerol at 4.5% by weight of the tobacco material. Table 1b shows that in aerosol generating materials prepared according to the present disclosure, the standard deviation of the total glycerol content within a given batch of material was in all cases less than 35%, or less than 30% or less than 25% of the mean.

Where the amorphous solid material comprises a flavoring agent, the overall flavoring agent of the article may comprise a flavoring agent provided in the amorphous solid material, optionally applied to tobacco material or to a component of the article other than the aerosol generating material 3 . Additional flavoring agents present may be included. The total flavor content of an article can be determined by disassembling the article into its component parts and performing chemical analysis as known to those skilled in the art to determine the flavor content of each component and hence the total flavor content. In instances where the amorphous solid comprises a flavoring agent, the total flavorant content of the article may be from 5 mg to 30 mg per article, such as from 16 mg to 22 mg per article, or from 5 mg to 10 mg per article or from 17 mg per article to 30 mg per article. . The amorphous solid may comprise at least 20% of the total flavor content.

Articles comprising an aerosol generating material according to the present disclosure have been prepared, wherein the aerosol generating material comprises 5 wt %, 12 wt % or 20 wt % of amorphous solids comprising 35 wt % menthol as a flavoring agent. Table 2 shows the menthol content (mg) per article for articles comprising an aerosol generating material. Standard deviations of menthol content were determined by analyzing 10 articles made from each batch of aerosol generating material. As shown, the total menthol inclusion of each article may vary from article to article by less than a standard deviation of less than 20% of the average menthol inclusion in mg.

The aerosol generating material may be provided in the form of a rod having a first end and a second end. A portion of the rod between the first end of the rod and an intermediate longitudinal position between the first and second ends may include between 20% and 80% of the amorphous solid material in the rod.

The mouthpiece 2 in the present example comprises a body of material 6 upstream of the hollow tubular element 4 , in this example adjacent and in abutting relation with the hollow tubular element 4 . The material body 6 and the hollow tubular element 4 each define a substantially cylindrical overall outer shape and share a common longitudinal axis. The material body 6 is wrapped in a first plug wrap 7 . Preferably, the first plug wrap 7 has a basis weight of less than 50 gsm, more preferably between about 20 gsm and 40 gsm. Preferably, the first plug wrap 7 has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. Preferably, the first plug wrap 7 is a non-porous plug wrap having, for example, a permeability of less than 100 Coresta units, for example less than 50 Coresta units. However, in other embodiments, the first plug wrap 7 may be a porous plug wrap, for example having a permeability of greater than 200 Coresta units.

Preferably, the length of the material body 6 is less than about 15 mm. More preferably, the length of the material body 6 is less than about 10 mm. Additionally or alternatively, the length of the material body 6 is at least about 5 mm. Preferably, the length of the material body 6 is at least about 6 mm. In some preferred embodiments, the length of the body of material 6 is from about 5 mm to about 15 mm, more preferably from about 6 mm to about 12 mm, even more preferably from about 6 mm to about 12 mm, most preferably from about 6 mm, 7 mm. , 8mm, 9mm or 10mm. In this example, the length of the material body 6 is 10 mm.

In this example, the material body 6 is formed from a filament tow. In this example, the tow used in the material body 6 has a denier per filament (d.p.f.) of 8.4 and a total denier of 21,000. Alternatively, for example, the tow may have a denier per filament (d.p.f.) of 9.5 and a total denier of 12,000. In this example, the tow comprises plasticized cellulose acetate tow. The plasticizer used in the tow comprises about 7% by weight of the tow. In this example, the plasticizer is triacetin. In other examples, other materials may be used to form the material body 6 . For example, rather than a tow, the body 6 may be formed of paper, for example, in a manner similar to paper filters known for use in cigarettes. Alternatively, body 6 may be formed from tows other than cellulose acetate, such as polylactic acid (PLA), other materials described herein for filamentary tows, or similar materials. The tow is preferably formed of cellulose acetate. The tow, whether formed of cellulose acetate or of other materials, preferably has a d.p.f. of at least 5, more preferably at least 6, even more preferably at least 7. This denier per filament value provides a tow with relatively coarse and thick fibers with a low surface area, which results in a lower d.p.f. It produces a pressure drop across the mouthpiece 2 that is lower than the tows with values. Preferably, to achieve a sufficiently uniform body of material 6, the tow has a denier per filament of 12 d.p.f. Hereinafter, preferably 11 d.p.f. Hereinafter, more preferably, it is 10 d.p.f or less.

The total denier of the tow forming the body of material 6 is preferably at most 30,000, more preferably at most 28,000, even more preferably at most 25,000. These total denier values provide a tow that occupies a reduced proportion of the cross-sectional area of the mouthpiece 2 , which results in a lower pressure drop across the mouthpiece 2 than tows with higher total denier values. For adequate rigidity of the body of material 6 , the tow preferably has a total denier of at least 8,000, more preferably of at least 10,000. Preferably, the denier per filament is between 5 and 12 and the total denier is between 10,000 and 25,000. More preferably, the denier per filament is between 6 and 10, and the total denier is between 11,000 and 22,000. Preferably, the cross-sectional shape of the filaments of the tow is a 'Y' shape, although in other embodiments other shapes may be used, such as 'X' shaped filaments, the same d.p.f. and total denier values.

1 , the mouthpiece 2 of the article 1 has an upstream end 2a adjacent the rod of the aerosol-generating substrate 3 and a downstream end 2b distal from the rod of the aerosol-generating substrate 3 . ) is included. At the downstream end 2b, the mouthpiece 2 has a hollow tubular element 4 formed from a filament tow. This has been found to advantageously significantly reduce the temperature of the outer surface of the mouthpiece 2 at the downstream end 2b of the mouthpiece which comes into contact with the mouth of the consumer when the article 1 is in use. It has also been found that the use of the tubular element 4 significantly reduces the temperature of the outer surface of the mouthpiece 2 even upstream of the tubular element 4 . Without wishing to be bound by theory, this indicates that the tubular element 4 channels the aerosol closer to the center of the mouthpiece 2 , thus reducing the transfer of heat from the aerosol to the outer surface of the mouthpiece 2 . It is assumed that because

In this example, the article 1 has an outer circumference of about 21 mm (ie the article is in a demi-slim form). In other examples, the article may be provided in any of the formats described herein having a perimeter of, for example, 15 mm to 25 mm. Since the article must be heated to emit the aerosol, improved heating efficiency can be achieved using articles with fewer perimeters within this range, for example perimeters of less than 23 mm. Article perimeters greater than 19 mm have also been found to be particularly effective to achieve improved aerosols through heating, while maintaining adequate product length. Articles with perimeters of 19 mm to 23 mm, more preferably 20 mm to 22 mm, have been found to provide a good balance between providing effective aerosol delivery while allowing efficient heating.

The perimeter of the mouthpiece 2 is substantially the same as the periphery of the rod of aerosol generating material 3 , so that there is a smooth transition between these components. In this example, the outer circumference of the mouthpiece 2 is about 20.8 mm. A tipping paper 5 is wrapped around the entire length of the mouthpiece 2 and over a portion of the rod of aerosol generating material 3 , inside it to connect the mouthpiece 2 with the rod 3 . It has an adhesive on its surface. In this example, the tipping paper 5 extends 5 mm above the rod of aerosol generating material 3 , but may alternatively extend 3 mm to 10 mm, or more preferably 4 mm to 6 mm above the rod 3 , It provides a secure attachment between the piece 2 and the rod 3 . The tipping paper 5 may have a basis weight higher than the basis weight of the plug wraps used in the article 1, for example a basis weight of 40 gsm to 80 gsm, more preferably 50 gsm to 70 gsm, and in this example is 58 gsm. It has been found that these ranges of basis weights allow the tipping papers to have acceptable tensile strength while being flexible enough to wrap around the article 1 and adhere to itself along the longitudinal lap seam on the paper. Once wrapped around the mouthpiece 2, the perimeter of the tipping paper 5 is about 21 mm.

The “wall thickness” of the hollow tubular element 4 corresponds to the thickness of the wall of the tube 4 in the radial direction. This can be measured using, for example, a caliper. The wall thickness is advantageously greater than 0.9 mm, more preferably greater than or equal to 1.0 mm. Preferably, the wall thickness is substantially constant around the entire wall of the hollow tubular element 4 . However, if the wall thickness is not substantially constant, the wall thickness is preferably greater than 0.9 mm at any point around the hollow tubular element 4 , more preferably greater than 1.0 mm.

Preferably, the length of the hollow tubular element 4 is less than about 20 mm. More preferably, the length of the hollow tubular element 4 is less than about 15 mm. Even more preferably, the length of the hollow tubular element 4 is less than about 10 mm. Additionally, or alternatively, the length of the hollow tubular element 4 is at least about 5 mm. Preferably, the length of the hollow tubular element 4 is at least about 6 mm.

Preferably, the density of the hollow tubular element 4 is less than about 0.75 grams/cubic centimeter (g/cc), more preferably less than 0.6 g/cc. In some embodiments, the density of the hollow tubular element 4 is 0.25 to 0.75 g/cc, more preferably 0.3 to 0.6 g/cc, even more preferably 0.4 g/cc to 0.6 g/cc or about 0.5 g. /cc. It has been found that these densities provide a good balance between the improved rigidity provided by the denser material and the lower heat transfer properties of the lower density material. For the purposes of the present invention, the “density” of the hollow tubular element 4 refers to the density of the filamentous tow forming the element into which any plasticizer is incorporated. The density can be determined by dividing the total weight of the hollow tubular element 4 by the total volume of the hollow tubular element 4 , where the total volume is for example using appropriate measurements of the hollow tubular element 4 taken using calipers. can be calculated by If necessary, appropriate dimensions can be measured using a microscope.

The filament tow forming the hollow tubular element 4 preferably has a total denier of less than 45,000, more preferably less than 42,000. It has been found that this total denier allows the formation of a tubular element 4 that is not too dense. Preferably, the total denier is at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filament tow forming the hollow tubular element 4 has a total denier of between 25,000 and 45,000, more preferably between 35,000 and 45,000. Preferably the cross-sectional shape of the filaments of the tow is a 'Y' shape, although other shapes may be used, such as 'X' shaped filaments in other embodiments.

The filament tow forming the hollow tubular element 4 preferably has a denier per filament of greater than three. It has been found that this denier per filament allows the formation of a tubular element 4 that is not too dense. Preferably, the denier per filament is at least 4, more preferably at least 5. In a preferred embodiment, the filament tow forming the hollow tubular element 4 has a denier per filament of from 4 to 10, more preferably from 4 to 9. In one example, the filament tow forming the hollow tubular element 4 has an 8Y40,000 tow formed of cellulose acetate and comprising 18% plasticizer, such as triacetin.

The hollow tubular element 4 preferably has an inner diameter of greater than 3.0 mm. Diameters smaller than this may increase the velocity of the aerosol passing through the mouthpiece 2 into the mouth of the consumer more than desired, so that the aerosol becomes too warm, for example at temperatures above 40°C or above 45°C. to reach More preferably, the hollow tubular element 4 has an inner diameter of greater than 3.1 mm, even more preferably greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the hollow tubular element 4 is about 3.9 mm.

The hollow tubular element 4 preferably comprises from 15% to 22% by weight of plasticizer. In the case of cellulose acetate tow, the plasticizer is preferably triacetin, although other plasticizers such as polyethylene glycol (PEG) may be used. More preferably, the tubular element 4 comprises 16% to 20% by weight plasticizer, for example about 17%, about 18% or about 19% plasticizer.

The hollow tubular element 4 in this example is a first hollow tubular element 4 , and the mouthpiece comprises a second hollow tubular element 8 , also called a cooling element, upstream of the first hollow tubular element 4 . do. In the present example, the second hollow tubular element 8 is upstream of, adjacent to, and in abutting relation to, the body of material 6 . The material body 6 and the second hollow tubular element 8 each define a substantially cylindrical overall outer shape and share a common longitudinal axis. The second hollow tubular element 8 is formed of a plurality of paper layers wound in parallel, with butted seams, to form the tubular element 8 . In this example, the first and second paper layers are provided as two ply tubes, but in other examples three, four or more paper layers may be used to form three, four or more ply tubes. . Other structures may be used, such as spirally wound paper layers, cardboard tubes, tubes formed using a Papie Mace type process, molded or extruded plastic tubes or the like. The second hollow tubular element 8 may also be formed using a rigid plug wrap and/or tipping paper as the second plug wrap 9 and/or tipping paper 5 described herein, which is a separate tubular This means that the element is not required. The rigid plug wrap and/or tipping paper is manufactured to have sufficient rigidity to withstand axial compressive forces and bending moments that may occur during manufacture and while the article 1 is in use. For example, the rigid plug wrap and/or tipping paper may have a basis weight of from 70 gsm to 120 gsm, more preferably from 80 gsm to 110 gsm. Additionally or alternatively, the rigid plug wrap and/or tipping paper may have a thickness between 80 μm and 200 μm, more preferably between 100 μm and 160 μm, or between 120 μm and 150 μm. In order to achieve an acceptable overall level of stiffness for the second hollow tubular element 8 , it may be desirable for both the second plug wrap 9 and the tipping paper 5 to have values in these ranges.

The second hollow tubular element 8 preferably has a wall thickness of at least about 100 μm and at most about 1.5 mm, preferably between 100 μm and 1 mm and more, which can be measured in the same way as the first hollow tubular element 4 . Preferably 150 μm to 500 μm, or about 300 μm. In this example, the second hollow tubular element 8 has a wall thickness of about 290 μm.

Preferably, the length of the second hollow tubular element 8 is less than about 50 mm. More preferably, the length of the second hollow tubular element 8 is less than about 40 mm. Even more preferably, the length of the second hollow tubular element 8 is less than about 30 mm. Additionally or alternatively, the length of the second hollow tubular element 8 is preferably at least about 10 mm. Preferably, the length of the second hollow tubular element 8 is at least about 15 mm.

In this example, the length of the second hollow tubular element 8 is 25 mm.

A second hollow tubular element 8 is positioned around and defines an air gap in the mouthpiece 2 acting as a cooling segment. The air gap provides a chamber in which the heated volatilized components generated by the aerosol generating material 3 flow. The second hollow tubular element 8 is hollow to provide a chamber for aerosol accumulation, but is rigid enough to withstand the axial compressive forces and bending moments that may occur during manufacture and while the article 1 is in use. The second hollow tubular element 8 provides a physical displacement between the aerosol generating material 3 and the material body 6 . The physical displacement provided by the second hollow tubular element 8 will provide a thermal gradient over the length of the second hollow tubular element 8 .

Preferably, the mouthpiece 2 comprises a cavity having an internal volume greater than 450 mm 3 . It has been found that providing a cavity of at least this volume allows for improved aerosol formation. This cavity size provides sufficient space within the mouthpiece 2 to allow the heated volatilized components to cool, thus generating an aerosol at higher temperatures than would otherwise be possible as these may generate an aerosol that is too warm. Allow the material 3 to be exposed. In the present example, the cavity is formed by the second hollow tubular element 8 , however in alternative arrangements it may be formed in another part of the mouthpiece 2 . More preferably, the mouthpiece 2 comprises, for example, a cavity formed in the hollow tubular element 8 , the cavity having an internal volume of greater than 500 mm 3 , more preferably greater than 550 mm 3 , so that the addition of aerosol Allow for improvement. In some examples, the interior cavity comprises a volume from about 550 mm 3 to about 750 mm 3 , such as about 600 mm 3 or 700 mm 3 .

The second hollow tubular element (8) comprises a heated volatilized component entering the first upstream end of the second hollow tubular element (8) and a heated volatilized component exiting the second downstream end of the second hollow tubular element (8). and may be configured to provide at least a 40 degree Celsius temperature difference between the components. The second hollow tubular element 8 is preferably a heated volatilized component entering the first upstream end of the second hollow tubular element 8 and heating exiting the second downstream end of the second hollow tubular element 8 . and provide a temperature difference between the volatilized components of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, more preferably at least 100 degrees Celsius. This temperature difference over the length of the second hollow tubular element 8 protects the temperature-sensitive body material 6 from high temperatures of the aerosol generating material 3 when heated.

In alternative articles, the second hollow tubular element 8 may be replaced by an alternative cooling element, for example an element formed of a material body which allows the aerosol to pass therethrough in the longitudinal direction and also performs the function of cooling the aerosol. can

In this example, the first hollow tubular element 4 , the material body 6 and the second hollow tubular element 8 are combined using a second plug wrap 9 wrapped around all three sections. Preferably, the second plug wrap 9 has a basis weight of less than 50 gsm, more preferably between about 20 gsm and 45 gsm. Preferably, the second plug wrap 9 has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. The second plug wrap 9 is preferably a non-porous plug wrap having a permeability of less than 100 Coresta units, for example less than 50 Coresta units. However, in alternative embodiments, the second plug wrap 9 may be a porous plug wrap having a permeability of, for example, greater than 200 Coresta units.

In this example, the aerosol generating material 3 is wrapped in a wrapper 10 . The wrapper 10 may be, for example, a paper or paper-backed foil wrapper. In this example, the wrapper 10 is substantially impermeable to air. In alternative embodiments, the wrapper 10 preferably has a permeability of less than 100 Coresta units, more preferably less than 60 Coresta units. Low permeability wrappers, for example having a permeability of less than 100 Coresta units, more preferably less than 60 Coresta units, have been found to result in an improvement in aerosol formation in the aerosol generating material 3 . Without wishing to be bound by theory, it is hypothesized that this is due to reduced loss of aerosol compounds through the wrapper 10 . The permeability of the wrapper 10 can be measured according to ISO 2965:2009 for the determination of air permeability to materials used as cigarette papers, filter plug wraps and filter binding papers.

In this embodiment, the wrapper 10 comprises aluminum foil. Aluminum foil has been found to be particularly effective in enhancing the formation of aerosols in the aerosol generating material 3 . In this example, the aluminum foil has a metal layer having a thickness of about 6 μm. In this example, the aluminum foil has a paper backing. However, in alternative arrangements, the aluminum foil may be of other thicknesses, for example between 4 μm and 16 μm in thickness. The aluminum foil also need not have a paper backing, but may have a backing formed of other materials, for example to help provide adequate tensile strength to the foil, or it may have no backing material. Metal layers or foils other than aluminum may also be used. The total thickness of the wrapper is preferably between 20 μm and 60 μm, more preferably between 30 μm and 50 μm, which can provide a wrapper with suitable structural integrity and heat transfer properties. The tensile force that can be applied to the wrapper before it breaks can be greater than 3,000 grams force, for example between 3,000 and 10,000 grams or between 3,000 and 4,500 grams.

The article has a ventilation level of about 75% of the aerosol drawn through the article. In alternative embodiments, the article may have a ventilation level of between 50% and 80%, such as between 65% and 75% of the aerosol drawn through the article. In some examples, the standard deviation of the ventilation level in a batch of articles made according to the present disclosure is less than 5%, or less than 4%, or less than 3%. To determine the standard deviation of ventilation levels, a batch refers to at least 10 articles manufactured to the same specifications. For example, these items provided as a pack of items can be used as the basis for a measurement. These standard deviations can be achieved due to improved blending of tobacco material and amorphous solid material in aerosol-generating material made in accordance with the present invention, which improved blending can result in more consistent packing of aerosol-generating material in articles. because there is

Ventilation at these levels helps to slow the flow of aerosol drawn through the mouthpiece 2 , thus allowing the aerosol to cool sufficiently before reaching the downstream end 2b of the mouthpiece 2 . do. Ventilation is provided directly to the mouthpiece 2 of the article 1 . In the present example, ventilation is provided to the second hollow tubular element 8 , which has been found to be particularly beneficial for assisting the aerosol generating process. Ventilation passes through first and second parallel rows of perforations 12, formed in this case with laser perforations, at positions 17.925 mm and 18.625 mm, respectively, from the mouth end 2b downstream of the mouthpiece 2 . provided through These perforations pass through the tipping paper 5 , the second plug wrap 9 and the second hollow tubular element 8 . In alternative embodiments, ventilation may be provided into the mouthpiece at other locations, for example into the material body 6 or the first tubular element 4 .

Preferably, the aerosol-generating material 3 is provided as a cylindrical rod of aerosol-generating material. Regardless of the shape of the aerosol generating material, it preferably has a length of about 10 mm to 100 mm. In some embodiments, the length of the aerosol generating material is preferably in the range of about 25 mm to 50 mm, more preferably in the range of about 30 mm to 45 mm, even more preferably in the range of about 30 mm to 40 mm.

The volume of the aerosol generating material 3 provided may vary from about 200 mm 3 to about 4300 mm 3 , preferably from about 500 mm 3 to 1500 mm 3 , more preferably from about 1000 mm 3 to about 1300 mm 3 . Provision of these volumes of aerosol generating material, for example from about 1000 mm 3 to about 1300 mm 3 , has been shown to advantageously achieve a good aerosol with greater visibility and sensory performance compared to that achieved with selected volumes at the lower end of the range. .

Advantageously, it has been found that providing a higher mass of aerosol generating material results in improved sensory performance compared to aerosols generated from lower mass tobacco material.

2A is a cross-sectional side view of a further article 1' comprising a capsule retaining mouthpiece 2'. FIG. 2B is a cross-sectional view through line A-A' of the capsule retaining mouthpiece shown in FIG. 2A. The article 1' and the capsule holding mouthpiece 2' are the same as the article 1 and the mouthpiece 2 shown in FIG. 1 , but the aerosol modifier is in this example a material body ( 6), except that the oil-resistant first plug wrap 7 ′ surrounds the material body 6 . In other examples, the aerosol modifier is provided in other forms, such as the material is injected into the body 6 of the material, or a flavoring agent or other aerosol modifier that may also be disposed within a thread, for example the body 6 of the material. It may be provided on a thread carrying the.

Capsule 11 may comprise a breakable capsule, for example a capsule having a hard, brittle shell surrounding a liquid payload. In this example, a single capsule 11 is used. The capsule 11 is completely embedded in the body 6 of the material. In other words, the capsule 11 is completely surrounded by the material forming the body 6 . In other examples, a plurality of breakable capsules may be disposed within the body 6 of material, for example two, three or more breakable capsules may be disposed. The length of the body 6 of material may be increased to accommodate the required number of capsules. In examples where multiple capsules are used, the individual capsules may be identical to each other, or may differ from each other in size and/or capsule payload. In other examples, bodies 6 of multiple materials may be provided, each body holding one or more capsules.

The capsule 11 has a core-shell structure. In other words, the capsule 11 comprises a shell encapsulating a liquid formulation, for example a flavoring agent or other agent, which may be any of the flavoring agents or aerosol modifiers described herein. The shell of the capsule may be ruptured by the user to release the flavor or other agent into the body 6 of the material. The first plug wrap 7 ′ may include a barrier coating that renders the material of the plug wrap substantially impermeable to the liquid payload of the capsule 11 . Alternatively or additionally, the second plug wrap 9 and/or tipping paper 5 renders the material of the plug wrap and/or tipping paper substantially impermeable to the liquid payload of the capsule 11 . It may include a barrier coating.

In this example, the capsule 11 is spherical and has a diameter of about 3 mm. In other examples, other shapes and sizes of the capsule may be used. The total weight of the capsule 11 may range from about 10 mg to about 50 mg.

In the present example, the capsule 11 is positioned in a longitudinal central position within the body 6 of material. That is, the capsule 11 is positioned so that its center is 4 mm from each end of the body 6 of material. In other examples, the capsule 11 may be positioned in a position other than the longitudinal central position in the body 6 of material, ie closer to the downstream end of the body 6 of material than the upstream end, or It may be located closer to the upstream end of the body 6 of material than to the downstream end. Preferably, the mouthpiece 2' is configured such that the capsule 11 and the vent holes 12 are longitudinally offset from each other in the mouthpiece 2'.

A cross-section of the mouthpiece 2' is shown in FIG. 2B, taken along line A-A' in FIG. 2A. 2b shows the capsule 11 , the material body 6 , the first and second plug wraps 7 ′, 9 and the tipping paper 5 . In this example, the capsule 11 is centered on the longitudinal axis (not shown) of the mouthpiece 2'. The first and second plug wraps 7 ′, 9 and the tipping 5 are arranged concentrically around the material body 6 .

The breakable capsule 11 has a core-shell structure. That is, the encapsulating material or carrier material creates a shell around the core comprising the aerosol modifier. The shell structure prevents movement of the aerosol modifier during storage of the article 1 , but may allow for controlled release of the aerosol modifier, also referred to as an aerosol modifier, during use.

In some cases, the barrier material (also referred to herein as an encapsulating material) is brittle. The capsule is crushed or otherwise ruptured or broken by the user to release the encapsulated aerosol modifier. Typically, the capsule is destroyed just before heating begins, however, the user can choose when to release the aerosol modifier. The term "breakable capsule" refers to a capsule in which the shell can be broken by pressure to release the core; More specifically, the shell may rupture under the pressure exerted by the user's fingers when the user wishes to release the core of the capsule.

In some cases, the barrier material is heat resistant. That is, in some cases, the barrier will not rupture, melt, or otherwise fail at the temperature reached at the capsule point during operation of the aerosol providing device. Illustratively, the capsule positioned in the mouthpiece may be exposed to temperatures in the range of, for example, 30° C. to 100° C., and the carrier material can continuously hold the liquid core to at least about 50° C. to 120° C.

In other cases, the capsule releases the core composition upon heating, for example, by melting of the barrier material or by capsule inflation resulting in rupture of the barrier material.

The total weight of the capsule may range from about 1 mg to about 100 mg, suitably from about 5 mg to about 60 mg, from about 8 mg to about 50 mg, from about 10 mg to about 20 mg, or from about 12 mg to about 18 mg.

The total weight of the core formulation may range from about 2 mg to about 90 mg, suitably from about 3 mg to about 70 mg, from about 5 mg to about 25 mg, from about 8 mg to about 20 mg, or from about 10 mg to about 15 mg.

The capsule according to the invention comprises a core and a shell as described above. The capsule may exhibit a crush strength of from about 4.5 N to about 40 N, more preferably from about 5 N to about 30 N or about 28 N (eg, from about 9.8 N to about 24.5 N). Capsule burst strength can be measured when the capsule is removed from the material body 6 , and a force gauge can be used to measure the force at which the capsule ruptures when pressed between two flat metal plates. A suitable measuring device is the Sauter FK 50 force gauge with a flat headed attachment, which can be used to crush the capsule against a flat, hard surface with a surface similar to the attachment.

The capsules may be substantially spherical and have a diameter of at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2.5 mm, 2.8 mm or 3.0 mm.

Illustratively, the capsule diameter may range from about 0.4 mm to about 10.0 mm, from about 0.8 mm to about 6.0 mm, from about 2.5 mm to about 5.5 mm, or from about 2.8 mm to about 3.2 mm. In some cases, the capsule may have a diameter of about 3.0 mm. These sizes are particularly suitable for incorporating capsules into articles as described herein.

For example, for a spherical capsule with a diameter of 3.0 mm, the maximum cross-sectional area of the capsule is 7.07 mm 2 . For a mouthpiece 2' having a perimeter of about 21 mm as described herein, the material body 6 has an outer perimeter of 20.8 mm, and the radius of this component is 3.31 mm, which corresponds to a cross-sectional area of 34.43 mm2. will be The capsule cross-sectional area is, in this example, 20.5% of the cross-sectional area of the mouthpiece 2'. As another example, if the capsule had a diameter of 3.2 mm, its maximum cross-sectional area would be 8.04 mm 2 . In this case, the cross-sectional area of the capsule will be 23.4% of the cross-sectional area of the material body 6 . The capsule having the greatest cross-sectional area of less than 28% of the cross-sectional area of the portion of the mouthpiece 2' provided with the capsule 11 has a greater pressure drop across the mouthpiece 2' compared to capsules having a greater cross-sectional area. reduced, and has the advantage that adequate space is left around the capsule for the aerosol to pass through without the material body 6 removing significant amounts of the aerosol mass as it passes through the mouthpiece 2'.

Preferably, the pressure drop or difference across the article (also referred to as resistance to aspiration), measured as opening pressure drop (ie, with the vent openings open), is reduced by less than 8 mmH ₂ O when the capsule is broken. . More preferably, the opening pressure drop is reduced by less than 6 mmH ₂ O, more preferably by less than 5 mmH ₂ O. These values are measured as the average achieved by at least 80 articles made of the same design. These small changes in pressure drop mean that other aspects of product design can be achieved, such as setting the correct aeration level for a given product pressure drop, regardless of whether the consumer chooses to destroy the capsule.

3 shows an example of a non-flammable aerosol providing device 100 for generating an aerosol from an aerosol generating medium/material, such as the aerosol generating material 3 of the articles 1 , 1 ′ described herein. Broadly speaking, the device 100 heats a replaceable article 110 comprising an aerosol generating medium, eg, an article 1 , 1 ′ described herein, to be inhaled by a user of the device 100 . It can be used to generate an aerosol or other inhalable medium. Device 100 and replaceable article 110 together form a system.

Device 100 includes a housing 102 (in the form of an outer cover) that surrounds and houses various components of device 100 . The device 100 has an opening 104 at one end through which an article 110 can be inserted for heating by the heating assembly. In use, article 110 may be fully or partially inserted into a heating assembly that may be heated by one or more components of the heating assembly.

The device 100 of this example includes a first end member 106 that attaches to the first end member 106 to close the opening 104 when the article 110 is not in place. and a lid 108 that can be moved with respect to the In FIG. 3 , the lid 108 is shown in an open configuration, however, the lid 108 can be moved to a closed configuration. For example, the user may cause the lid 108 to slide in the direction of arrow “B”.

Device 100 may also include a user-operable control element 112 , such as a button or switch, that when pressed, activates device 100 . For example, a user may turn on device 100 by actuating switch 112 .

Device 100 may also include electrical components, such as socket/port 114 , that may receive a cable for charging a battery of device 100 . For example, socket 114 may be a charging port, such as a USB charging port.

4 depicts the device 100 of FIG. 3 with the outer cover 102 removed and the article 110 not present. Device 100 defines a longitudinal axis 134 .

4 , a first end member 106 is arranged at one end of the device 100 and a second end member 116 is arranged at an opposite end of the device 100 . The first and second end members 106 , 116 together at least partially define end surfaces of the device 100 . For example, a bottom surface of the second end member 116 at least partially defines a bottom surface of the device 100 . The edges of the outer cover 102 may also define some of the end surfaces. In this example, lid 108 also defines a portion of a top surface of device 100 .

The end of the device closest to the opening 104 may be known as the proximal end (or mouth end) of the device 100 because it is closest to the user's mouth during use. In use, the user inserts the article 110 into the opening 104 , manipulates the user control 112 to initiate heating of the aerosol generating material, and aspirates the aerosol generated by the device. This causes the aerosol to flow through the device 100 along the flow path towards the proximal end of the device 100 .

The other end of the device furthest from the opening 104 may be known as the distal end of the device 100 as it is the end furthest from the user's mouth during use. As the user inhales the aerosol generated by the device, the aerosol flows away from the distal end of the device 100 .

Device 100 further includes a power source 118 . Power source 118 may be, for example, a battery, such as a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (eg, lithium-ion batteries), nickel batteries (eg, nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to the heating assembly to supply electrical power when needed under the control of a controller (not shown) to heat the aerosol generating material. In this example, the battery is connected to a central support 120 that holds the battery 118 in place.

The device further comprises at least one electronics module 122 . The electronic module 122 may include, for example, a printed circuit board (PCB). PCB 122 may support at least one controller, such as a processor, and memory. The PCB 122 may also include one or more electrical tracks to electrically connect the various electronic components of the device 100 to each other. For example, battery terminals may be electrically connected to PCB 122 such that power may be distributed throughout device 100 . Socket 114 may also be electrically coupled to the battery via electrical tracks.

In the example device 100 , the heating assembly is an induction heating assembly and includes various components for heating the aerosol generating material of the article 110 through an induction heating process. Induction heating is the process of heating an electrically conductive object (such as a susceptor) by electromagnetic induction. An induction heating assembly may include an inductive element, eg, one or more inductor coils, and a device for passing a variable current, such as an alternating current, through the inductive element. A variable current in an inductive element generates a changing magnetic field. The changing magnetic field penetrates the susceptor properly positioned relative to the inductive element and creates eddy currents inside the susceptor. The susceptor has an electrical resistance to eddy currents, so the flow of eddy currents to this resistance causes the susceptor to be heated by Joule heating. In cases where the susceptor comprises a ferromagnetic material, such as iron, nickel or cobalt, heat is also removed from the magnetic material by hysteresis losses in the susceptor, ie as a result of the alignment of the magnetic dipoles with a changing magnetic field. can be created by various orientations of the magnetic dipoles of In induction heating, compared to heating by conduction, for example, heat is generated inside the susceptor to allow rapid heating. Moreover, no physical contact is required between the induction heater and the susceptor, allowing for increased freedom in construction and application.

The induction heating assembly of the exemplary device 100 includes a susceptor arrangement 132 (referred to herein as a “susceptor”), a first inductor coil 124 and a second inductor coil 126 . The first and second inductor coils 124 and 126 are made of an electrically conductive material. In this example, the first and second inductor coils 124 , 126 are made of a Litz wire/cable that is wound in a helical configuration to provide the helical inductor coils 124 , 126 . Litz wires include a plurality of individual wires that are individually insulated and twisted together to form a single wire. Litz wires are designed to reduce skin effect losses in the conductor. In the example of device 100 , first and second inductor coils 124 , 126 are made of copper litz wire having a rectangular cross-section. In other examples, the litz wire may have other shaped cross-sections, such as circular.

The first inductor coil 124 is configured to generate a first varying magnetic field for heating the first section of the susceptor 132 , and the second inductor coil 126 energizes the second section of the susceptor 132 . and generate a changing second magnetic field for heating. In this example, first inductor coil 124 is adjacent to second inductor coil 126 in a direction along longitudinal axis 134 of device 100 (ie, first and second inductor coils 124 ). , 126) do not overlap). The susceptor arrangement 132 may include a single susceptor, or two or more separate susceptors. Ends 130 of the first and second inductor coils 124 and 126 may be connected to the PCB 122 .

It will be appreciated that the first and second inductor coils 124 , 126 may, in some examples, have at least one characteristic different from each other. For example, the first inductor coil 124 may have at least one characteristic different from that of the second inductor coil 126 . More specifically, in one example, the first inductor coil 124 may have a different inductance value than the second inductor coil 126 . In FIG. 4 , first and second inductor coils 124 , 126 have different lengths such that first inductor coil 124 is wound over a smaller section of susceptor 132 than second inductor coil 126 . . Accordingly, the first inductor coil 124 may include a different number of turns than the second inductor coil 126 (assuming the spacing between the individual turns is substantially equal). In another example, the first inductor coil 124 may be made of a different material than the second inductor coil 126 . In some examples, the first and second inductor coils 124 , 126 may be substantially the same.

In this example, the first inductor coil 124 and the second inductor coil 126 are wound in opposite directions. This can be useful when the inductor coils are activated at different times. For example, initially, the first inductor coil 124 may operate to heat a first section/portion of the article 110 , and later, the second inductor coil 126 may operate a second inductor coil 126 of the article 110 . It can operate to heat the section/part. Winding the coil in opposite directions helps to reduce the current induced in the inactive coil when used with certain types of control circuitry. In FIG. 4 , the first inductor coil 124 is a right-hand helix, and the second inductor coil 126 is a left-hand helix. However, in other embodiments, the inductor coils 124 and 126 may be wound in the same direction, or the first inductor coil 124 may be a left hand spiral and the second inductor coil 126 may be a right hand spiral. .

The susceptor 132 in this example is hollow and thus defines a receptacle in which the aerosol generating material is received. For example, the article 110 may be inserted into the susceptor 132 . In this example, the susceptor 120 is tubular with a circular cross-section.

The susceptor 132 may be made of one or more materials. Preferably, the susceptor 132 comprises carbon steel with a coating of nickel or cobalt.

In some examples, the susceptor 132 can include at least two materials that can be heated at two different frequencies for selective aerosolization of the at least two materials. For example, a first section of the susceptor 132 (heated by the first inductor coil 124 ) may include a first material, and a susceptor (heated by the second inductor coil 126 ) ( The second section of 132 may include a second different material. In another example, the first section may include first and second materials, wherein the first and second materials may be heated differently based on operation of the first inductor coil 124 . The first and second materials may be adjacent along an axis defined by the susceptor 132 , or may form different layers within the susceptor 132 . Similarly, the second section may include third and fourth materials, wherein the third and fourth materials may be heated differently based on the operation of the second inductor coil 126 . The third and fourth materials may be adjacent along an axis defined by the susceptor 132 , or may form different layers within the susceptor 132 .

8 illustrates a first method of making an aerosol-generating material, eg, an aerosol-generating material for use in an article for use in a non-flammable aerosol providing system.

In step S101, the amorphous solid material of a single thickness in the form of a sheet is supplied to the crushing device. This can be achieved, for example, by providing a bobbin of amorphous solid sheet material that can be continuously fed to the crushing device. Alternatively, individual portions of amorphous solid material in the form of sheets, such as sheets known to those skilled in the art as flags, may be fed to the crusher. The inventors have surprisingly found that there are advantages to the amorphous solid material in sheet form when crushed to a single sheet thickness, as opposed to a conventional tobacco cutting process in which several sheets of lamina material are fed simultaneously to a cutting device. Feeding multiple thicknesses of amorphous solid sheet material to the shredding device in a single pass tends to result in uneven distribution of the material in the final aerosol generating material, as the sheet materials of multiple thicknesses can potentially bond together and cause the formation of clumps. have. Alternatively, amorphous solid sheet material of different thicknesses may be fed to the crushing apparatus in a single pass, for example where the 'tackiness' of the amorphous solid sheet is relatively low and the formation of lumps is avoided.

In step S102, the single-thickness amorphous solid material is shredded to obtain strips of amorphous solid material having a defined cut width. Optionally, the amorphous solid material may be subjected to a second cutting step, such as a cross cut type fracturing process, to obtain a defined cut length.

In step S103, the strips of the amorphous solid material obtained in step S102 are mixed with tobacco material. The inventors have found that, advantageously, the mixing of the crushed amorphous solid material with the tobacco material should preferably be carried out as soon as possible after step S102. The inventors believe that long-term storage of crushed amorphous solid material may result in a mass of amorphous solid debris forming in the crushed material, whereby the crushed amorphous solid material is mixed with tobacco material and an article as described herein is produced. It has been found that, when used to form, clumps of amorphous solid material result in an uneven distribution of the amorphous solid material between articles and within individual rods of aerosol generating material.

In some embodiments, the crushed amorphous solid material is incorporated into the tobacco material less than 12 hours, such as less than 6 hours, or less than 4 hours, or less than 2 hours, or less than 1 hour after the cutting step. Optionally, the crushed amorphous solid material may be fed to the tobacco material in an online process such that the time between crushing the amorphous solid material and incorporation of the crushed material into the tobacco material to form the final aerosol generating material is 30 seconds. less than, for example less than 20 seconds, or less than 10 seconds.

In some embodiments, a method of generating an aerosol generating material comprises cutting a sheet of amorphous solid material to form a plurality of strips of amorphous solid material having a cut length of at least about 5 mm, or at least about 10 mm, or at least about 20 mm. includes steps. In some embodiments, the method comprises removing the amorphous solid material to form a plurality of strips of amorphous solid material each having a cut length of about 5 mm to about 60 mm, or about 10 mm to about 55 mm, or about 20 mm to about 50 mm. cutting the sheet.

The mixing step may be performed using a rotary drum blender, for example, rotating at 5 to 30 RPM, for example 10 to 15 RPM. The drum diameter can be 0.8m to 1.2m, 5 sets of 10-20 pins (optional) project from the inner walls of the drum towards the center of the drum, the pins are 5% to 15% of the drum diameter, eg For example, it has a length of about 10%, the pins of each set are spaced longitudinally along the length of the drum and each set is spaced around the inner circumference. The angle of the central axis of the drum during the mixing operation may be approximately 10 to 30 degrees from horizontal (open side up). Batches of 5 to 20 kg (typically 8 to 10 kg) of total solids can be mixed in this drum, with a mixing time of 30 seconds to 10 minutes (eg 30 seconds to 2 minutes).

Alternatively, the mixing step may be integrated into a standard primary manufacturing process for tobacco material using, for example, an add-back line and flavor mixing cylinder. This method may be suitable for larger amounts of materials. A continuously rotating drum blender may be used, which is fed by two metering conveyors, each conveying one component (cut amorphous solid material such as tobacco material or crushed gel) at an accurate relative kg/hr speed. (rate) to achieve the desired level of amorphous solids inclusion in the aerosol generating material. The components are blended in a rotating drum blender as they pass and are collected at the outlet. Typical dimensions and operating conditions of a continuously rotating drum blender are RPM of 12 to 15 RPM, drum diameter of 0.6 to 0.8 m, drum length of 2.0 to 3.0 m. The residence time of the materials in the drum may be between 30 and 120 seconds (typically between 40 and 70 seconds).

9 illustrates a second method of making an aerosol-generating material, eg, an aerosol-generating material for use in an article for use in a non-flammable aerosol providing system. The second method may be performed using the equipment described in connection with the first method above, and those skilled in the art will recognize that the steps of the first and second methods may be appropriately combined. The method includes cutting ( S201 ) a first portion of the amorphous solid material to form a first component comprising a plurality of strips of the amorphous solid material having a first length. The method also includes cutting ( S202 ) the second portion of the amorphous solid material to form a second component comprising a plurality of strips of the amorphous solid material having a second length different from the first length. In step S203, the cut strips of amorphous solid material are mixed with tobacco material comprising strips and/or strands of tobacco material. Using two or more different lengths of the amorphous solid material may enable the size of the strips of the amorphous solid material to more closely match the material size distribution of the tobacco material, and consequently the greater of the amorphous solid and the tobacco material. resulting in good mixing.
